EBER HUBBARD, OF ST. JOSEPH, MICHIGAN, ASSIGNOR TO A. H. MORRISON, OF SAME PLACE.

PAPER=PULP PAIL.

SPECIFICATION forming part of Letters Patent No. 234,405, dated November 16, 1880.

Application filed March 25, 1880. (No model.)

10 all whom it may concern:

Be it known that I, EBER HUBBARD, of St. Joseph, in the countyof Berrien and State of Michigan, have invented certain new and useful lin 'irovements in Paper-Pulp Pails; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, in which.-

Figure l is a perspective view, and Fig. 2 is a vertical section.

Similar letters of reference indicate correponding parts in all the figures.

My invention relates to improvements in pulp pail-bodies; and it consists of a paiIbody made of pulp thickened at its lower end and gradually diminishing in thickness toward its upper end, where it is thinnest,-and provided with a croze near its thickened lower end for the reception of the bottom, as hereinafter more fully set forth.

In the drawings, A is the pulp-body of apail, which is of the usual conical shape, of pressed pulp, the walls of said body increasing in thickness from the upper rim, a, downward to the bottom rim, 1).

c is the inside groove or croze, which is formed by a detachable and adjustable rib upon the inside mold, upon which the pail is pressed by compressing that part of the pulp. Into this the bottom is inserted in the usual manner.

By constructing the body of the pulp-pail, as above described, with its lower end thickest and gradually tapering or diminishiu gin thick- .gradually diminishing in thickness toward its ness toward its upper end, which is made thinnest, the body of the pail, is made lighter than in the ordinary construction, in which the body of the pail is made of the same thickness throughout, and the body is rendered stronger at its lower part, where it is most subject to strain and jars, and where the body is materially weakened by the croze formed therein for the insertion of the bottom.

I am aware that a pulp pailbody has heretofore been made with a croze near its lower end for the bottom, formed during the process of pressing the pail-body or formed after the pail-body is pressed, and I therefore lay no claim to such constructions.

I am al o aware of the patents of E. I-Iubhard for a paper-pulp pail, dated May 28,1878, No. 204,223, and M. E. Hubbard for a machine for making pails from paper-pulp, dated April 16, 1878, No. 202,547, and I therefore lay no claim to such inventions.

Having thus described my improvement, I claim and desire to secure by Letters Patent of the United States- As a new article of manufacture, the pulp pail-body A, thickened at its lower end and 5 upper end, which is made thinnest, and provided with the croze 0 near its lower end for the reception of its bottom, substantially as described, and for the purpose set forth.

In testimony that I claim the foregoing as my own 1 have hereunto affixed my signature in presence of two witnesses.

EBER HUBBARD.
